Use Unit Price to Find the Cost of Any Amount

Start with Find the Unit Rate so dividing for 1 unit is familiar before the better buy and comparison pages. Use the unit analysis pages last, and have students write the units with every answer, such as feet per second.

Find the unit price in 4 problems, like 6 pens for $4.50, then the cost of a new amount. The unit price is the cost of 1 item or 1 unit, such as $3 per box. The directions on the page read: Find the unit price first. Then use it to find the new cost. Show your work in the space under each problem. Write money to the nearest cent. An answer key is included.

Yes, both. We made it for 6th Grade ratios, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with rates and unit rates. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Divide the first quantity by the second. Ava drove 186 miles in 3 hours, so 186 ÷ 3 = 62 miles per hour. A hose that fills a 150-liter tank in 8 minutes flows 18.75 liters per minute.

Find the unit price of each package by dividing the price by the number of units, then pick the lower one. Cereal at 12 oz for $3.48 is $0.29 per oz and 18 oz for $4.99 is $0.28 per oz, so the larger box is the better buy.

Multiply by a conversion factor written as a fraction so the old unit cancels. 120 feet per minute × (1 minute over 60 seconds) = 2 feet per second.

A percent is a rate per 100. On a hundred grid each square is 1 percent, so 37 shaded squares are 37%, 37/100 or 0.37.
